										//
										//  COMMENTS:
										//
										//    To get a Ribbon to display, the Ribbon framework must be initialized. 
										//    This involves three important steps:
										//      1) Instantiating the Ribbon framework object (CLSID_UIRibbonFramework).
										//      2) Passing the host HWND and IUIApplication object to the framework.
										//      3) Loading the binary markup compiled by UICC.exe.

	// Next, we create the application object (IUIApplication) and call the framework Initialize method,

	// that was provided to the framework earlier, allowing command handlers to be bound to individual
	// commands.
